QUICK-OPENING WATER-GLASS VALVE.

Application filed July 9, 1925..

This invention has for one or" its objects the provision of a novel, simple and inexpensive valve which while capable of gen-V eral use shall be especially adapted for use in connecting gage glasses to steam boilers and which shall embody means by which it ran be quickly opened or closed manually.

With the above and other objects in view, the invention consists of the construction, combination and arrangementof parts hereinafter' fully described and claimed, and illustrated in the accompanying drawing, wherein:

Figure 1 is a view partly in vertical section and partly in elevation illustrating the application of valves embodying my invention, and

Figure 2 is a sectional view taken on a vertical plane extending longitudinally and centrally through the valve.

Corresponding and like parts are referred to in the following description and designated in the accompanying drawing by similarV reference characters.

1n the drawing 1 designates a fragmentary portion of a steam boiler and 2 a gage glass connected to the boiler by Valves 3 embodying my invention.

Each valve comprises a body 4, a stem extending axially from one end of the body 4 and threaded as at 6 for connection with the boiler 1, a threaded nipple 7 extending laterally from the body 4 and a threaded hollow boss 8 extending axially from the other end of the body 4. At the juncture ot the body 4 and stem 5 the valve is provided with a seat 9. A cap nut 10 provided with a sleeve 10u is threaded on the boss 8, and a. packing ring 11 is positioned between the inner end ot the cap nut 10 and the body 4 and a packing washer 12 between the cap uut and the outer end of the boss 8. A stem 13 is slidably and rotatably mounted in the boss 8 and sleeve 10a and is provided with a conical inner end 14 and a polygonal outer end 15 from which latter end extends -a threaded stud 16. In its outer side the sleeve 1 0"i is provided with a quick acting spiral groove 17 in which is positioned the inner end of a pin 18 slidably mounted in the bore 19 of a handle 20. The pin 18 "and handle 2O are arranged axially or radiallyu with rares t@ the Sleeve 10a eed. the .See

18, and the pin 18 is held in the groove 17 by a spring 21 positioned between the inner end of the pin and the inner end wall of thc bore 19. At its inner end the handle 2O is provided with an arm 22 arranged at right angles with respect thereto and in parallel relation with respect to the sleeve l()a and stem 13. The arm 22 is provided at its outer end with an angular ear or lug 23 providedk with a polygonal opening 24 for the reception of the polygonal end 15 of the stem 13. A nut 25 applied to the stud 16 retains the handle 2O on the stern 13.

In practice the valves 3 are secured to the boiler 1 and the gage glass 2 to the nipples 7 in the manner illustrated in Figure 1.

l/Vhen it is desired to either open or close the valves 3 the handles 2O are swung about the sleeves 10a in the required direction. As the pins 18 engage in the grooves 17 the swinging movement of the handles 20 will either caus-e the stems 13 to move in the direction of oraway from the seats 9, and as the grooves 17 are of a quick acting type the stems 13 willhave imparted thereto a rapid endwise movementwith the result that the valves can be quickly closed or opened. The packing disks 12 establish leak proof connections between the stems 13 and the bodies 4.

It should be understood that the drawing is merely illustrative and does not pretend to give exact proportions Furthermore, the said drawing is illustrative of apreferred construction, it being my expectation that various changes and modications may be made without departing from the spirit and scope of my invention.

`VVhat is claimed is 1. A valve comprising a body provided with a seat, a sleeve connected to the body and provided with an external spiral groove, a stem slidably and rotatably mounted in the body and sleeve, an arm arranged parallel to the steln and secured at its outer end to thevouter end thereof, a handle secured to the inner end of the arm, andra spring pressed pin carried by the handle-and enl gaging in said spiral groove.

2. A valve comprising a body-provided with a seat and an external spiral groove, a stem mounted in the body :forV movement este @as eff ef @at an @emi-11s meer A .A n 1,590,818
